land subsidence

基本解釋

This decrease in the water table is a major contributor to land subsidence — New Orleans, like Venice, is sinking.
地下水位的降低則是地表陷沒(méi)的元兇，而新奧爾良，和威尼斯城一樣，正在下陷。
Buried tidal marsh or coastal forest soils point to sudden land subsidence of about 1 meter occurring at the same time from Vancouver Island to Northern California.
埋在地下的潮汐沼澤及沿海森林土壤使溫哥華至加利福尼亞州北部一帶的地面沉降1米左右。
"Other key factors are land subsidence caused by human activities, including over-exploitation of groundwater and massive construction of high buildings in coastal areas, " Liu said.
其他的重要因素是由人類自身活動(dòng)，如地下水的過(guò)度開(kāi)采，沿海地區(qū)高層建筑物的過(guò)度建設(shè)，所導(dǎo)致的地面沉降

Other aspects of climate change and land subsidence significantly exacerbate this effect though the relative importance of these factors varies from location.
